Abstract

The utility model relates to a swing arm for vehicle which is particularly applicable as a front suspension swing arm on ultra miniature car, reversed type motor tricycle, four-wheel motor cycle, and small four-wheel tractor. The swing arm is a parallelogram-shaped four link mechanism consisting of an upper swing arm, a lower swing arm, a swing arm brace, an upper button head seat, a lower button head seat and button heads. The swing arm can ensure that fore wheels of the vehicle are always perpendicular to ground instead of being splayed when the vehicle runs with load.

Description

Swing arm for vehicle
Technical field
The utility model relates to the front suspension swing arm of vehicles such as a kind of Swing arm for vehicle, particularly baby car, Reverse motor tricycle, four-wheel motor cycle, small four-wheel tractor.
Technical background
At present, the front suspension swing arm of many vehicles is to adopt Mai Fuxun mechanism's swing arm and four-bar linkage swing arm basically, the swing arm of Mai Fuxun mechanism is when vehicle body bears constant weight, often make the vehicle front-wheel axis with respect to the horizontal plane produce skew, it is perpendicular to the ground that front-wheel can not keep, thereby make the vehicle front-wheel be " eight " font, had a strong impact on the vehicle operation performance.The four-bar linkage swing arm is by last, following swing arm, the swing arm support, on, following ball cap and attaching parts thereof constitute, wherein go up, following swing arm one end respectively with the swing arm support on, the lower end is hinged, on, the other end of following swing arm is welded with respectively, following ball cap, and on, following ball cap is connected by attaching parts and forms parallelogram four-bar linkage, on wherein connecting, the attaching parts of following ball cap is one " U " shape piece and two ball screws, the bulb end of two ball screws lays respectively at and is welded on, in the ball cap of following swing arm end, " U " shape piece is fastened on two ball screws with nut.Be that swing arm support and horizontal surface with this four-bar linkage swing arm vertically is welded on the vehicle frame of vehicle during installation, and the vehicle front-wheel axle is welded on this four-bar linkage swing arm " U " shape piece bottom surface, because whole swing arm is the four-bar linkage of a parallelogram, when the clamp nut on the ball screw did not take place to become flexible, it is perpendicular to the ground that the vehicle front-wheel then can keep.But in the vehicle ' process, the loosening of nut that ball screw tightens " U " shape piece is inevitable, this just makes will produce relative displacement between " U " shape piece and ball screw inevitably, thereby make vehicle when bearing constant weight, its front-wheel will can not keep vertical with ground, so the swing arm of this kind four-bar linkage still can make vehicle front-wheel be " eight " font and influence the vehicle operation performance when load-carrying vehicle travels.
The utility model content
Technical problem to be solved in the utility model provides a kind of four-bar linkage front suspension swing arm of vehicle, makes the vehicle that possesses the swing arm of this kind structure when load-carrying is travelled, and its front-wheel can remain perpendicular to the ground.
Swing arm for vehicle described in the utility model is made of upper and lower swing arm, swing arm support, upper and lower ball cap and attaching parts thereof, wherein upper and lower swing arm one end is hinged with the upper and lower end of swing arm support respectively, the other end of upper and lower swing arm is welded with upper and lower ball cap respectively, and upper and lower ball cap is connected by attaching parts and forms parallelogram four-bar linkage, and the described attaching parts that is used to connect upper and lower ball cap is the ball head connecting rod that two ends are bulb.
Swing arm support and horizontal surface with this four-bar linkage swing arm during installation vertically are welded on the vehicle frame of vehicle, the vehicle front-wheel axle then vertically is welded on the ball head connecting rod of this four-bar linkage swing arm, when this swing arm can guarantee that vehicle load travels, the vehicle front-wheel remained perpendicular to the ground and can not be " eight " font
Swing arm for vehicle described in the utility model is owing to be on the basis of existing four-bar linkage swing arm, the attaching parts that is connected upper and lower ball cap that replaces former cause " U " shape piece and two ball screws and nut formation with holistic ball head connecting rod, thereby just can not occur owing to produce relative displacement between loosening causing " U " the shape piece of nut and ball screw, then cause the load-carrying vehicle front-wheel to be the situation of " eight " font, it is perpendicular to the ground that the vehicle front-wheel is remained, effectively prevented the wearing and tearing of vehicle front-wheel, and can make front-wheel steering more flexible accurately.
Description of drawings
Now in conjunction with the accompanying drawings the utility model is described in further detail.
Fig. 1 is the scheme drawing of a kind of concrete structure of Swing arm for vehicle described in the utility model;
Fig. 2 is its working state schematic representation during as left swing arm.
The specific embodiment
As shown in Figure 1, this Swing arm for vehicle is made of the ball head connecting rod 11 that upper and lower swing arm 2,6, swing arm support 4, upper and lower ball cap 7,8 and two ends thereof are bulb, wherein upper and lower swing arm 2,6 one ends are hinged with the upper and lower end of swing arm support 4 respectively, the other end of upper and lower swing arm 2,6 is welded with upper and lower ball cap 7,8 respectively, and upper and lower ball cap 7,8 is connected by ball head connecting rod 11 and forms parallelogram four-bar linkage.
As shown in Figure 2, the swing arm support 4 with this four-bar linkage swing arm during installation vertically is welded on the vehicle frame 1 of vehicle with horizontal surface, and vehicle front-wheel axle 9 then vertically is welded on the ball head connecting rod 11 of this four-bar linkage swing arm.When vehicle body bears weight or front-wheel and is subjected to impacting, front shock absorber 12 shrinks, top link 2 and following swing arm 6 are rotated around last rotating shaft 3 and lower rotary shaft 5 respectively, ball head connecting rod 11, front wheel spindle 9 and front-wheel 10 are also along with moving, because whole swing arm is a parallelogram four-bar linkage, then ball head connecting rod 11 remains vertically with horizontal surface, and vehicle front-wheel 10 also remains perpendicular to the ground.
Turning to by straight and horizontal adjusting rod 13 of front-wheel 10 realizes that straight and horizontal adjusting rod 13 1 ends are connected with front wheel spindle 9, and the other end is connected with the direction post.When turning to, the direction post rotates drive straight and horizontal adjusting rod 13 and moves, thereby drives front wheel spindle 9 swings, and front wheel spindle 9 swings drive front-wheel 10 and swing, and realize turning to.
